SPECIFICATION formingpart of Letters Patent No. 228,585, dated June 8,1880,

' Application flledMay 3, 1a19.

To all whom it may concern:

Be it known that we, FRANK'ANDERSON, of Peekskill, in the county ofWestchester and State of New York, and THEODORE M. FOOTE,

50f llewYork city, New York, have'invented certain new and usefulI-mprovementsin Meohtom of transmitting positive and negative currentsover a line or conductor by means of perforated paper, whereby, aftereach recording impulse is sent, an impulse of opposite po- '2 5 larityis transmitted for freeing the line and insuring legibility of thecharacters-at the re-.

' ceiving-instruinent.

The last-mentioned patent relates to a system of transmission ofnegative and positive 0 currents over a line or conductor by means ofperforated paper, whereby alternate currents of positive and negativeelectricity are transmitted over a circuit and each impulse madeavailable lor recording at the receiving-instrument. 1

The present invention is specially adapted to perlbratin g the paperfillets employed in the above-mentioned systems oi'telegraphy. It isfurther designed to provide a means by which 40 thcspacebetweentheletters, usuallyleft blank, is perforated wholly or in part by asingle row of peribrntions, the object being to record in the spacebetween each two letters, usually left blank, a series of dots in onerow, which, 5 in long lines, the recordingourrent having beentransmitted from one pole of the battery,

will be lengthened out and invariably recorded as a dash, in any case,however, distinctively marking the space between the letters.

It is essential'inthese systems. that the component perforations forming'the integral perforations representing the characters should alternate,and as the characters of the Morse, international, and othercharacter-alphabets employed are composed of an even and uneven numberof integral component 1 arts,'the perforations would not alwaysalternate properly. Therefore mechanism for eifecting this is of vitalimportanceto the transmission of a telegraphic message by alternatingcurrents of positive and negative electricity.

The present invention is especially designed to produce the perforationsin the paper employed inthe above-mentioned systems.

The special features of the invention consun; in the mechanismforoperatin g the punches and selecting the number necessary to form theperfiorations corresponding to each character to beproduced at thereceiving-instrumcntfor alteimating or reversing the position of theperforations when characters of an uneven number of parts succeed eachother in order to prevent two positive or two negative impulses fromfollowing each other, which would preventthe proper alternation in theour- 7 5 I rent necessary to produce the characters at thereceiving-instrument, and to provide for automatically feeding the paperin proper varying lengths, as more fully hereinafter set forth.

In the drawings; Figure 1- represents a top view of our improvedapparatus. Fig. 2' represents a sectional View on the line was of Fig.

1. Fig. 3 represents a side elevation. ofthe apparatus; Fig. 4, adetached view of the mechanism for operating the bar carrying the 8 5punching and paper-feeding mechanism. Pi 5 represents a detached view ofthe mechanism for operating the punch-selecting bars. Fig; 6 representsa diagram of a perforated paper for producing the impulses. Fig. 7represents de- 9o tached views of the punch-head and punches; and Figs.8,9, 10, and 11 diagrams representing tne ditfercnt methods of formingthe perforations.

The let-ter'l. represents a continuously-re; 5 volving shaft driven byany suitable power. Said shaft'has rigidly secured to it a ratchet.wheel g', and has mounted on it aloose sleeve,

2' v I ceases J, which. carries" two cam-disks, H M,adapted apawl orclutch,

' a normal position by means of a short lever,

m, pi\ 'o'ted to the stan 'lard,,and while in said position engages theend of the pawlor clutch h and holds it away from the ratchet-wheel j,permitting the shaft I to revolve independently of the,slee ve J and itsattachments.

The letter P indicatesa'reciprocating latchbar, connected, byneans of anangle-lever, g, and bar W", with an oscillatingframe, Q, pivoted insuitable bearings andextending transversely .below the key-levers,hereinafter more. fully described, so as to be oscillated thereby. whenone of such levers is depressed, the said frame being held in a normalposition by means;

at a spring. The said bar IP is provided near its forward end with anupright projectiomp,

which sets directly under the lower arm of the an gle-lever i, Fig. 4,and forward of said projection is provided. with a shoulder, which serveto engage the lower end of the lever m and trip it when the bar 7 isdrawn back by All!) depression of one of the keylevers, so as .torelease the angle-lever and permit it to be shifted by 1 ne ans of thespring Z, fro1n its normal position. The lower arm of said angle--lever, when in its normal position, engages the lower end of the pawlorclutch h and holds it away from the ratchet j on the shaft; but whenit is shifted it releases said pawl. which will be thrown into gear withthe ratchet-wheel by means of the spring I, so as to carry the sleeve Jwith the rotating shaft.

The disk H on the sleeve J is provided at its periphery with aprojection, at, which serves to trip the angle-leveri '5 after thesleeve has completed one revolution and return said lever to its normalpositiomso as to engage the lower end of the clutch or pawl h andrelease it from the ratchet-wheel.

Thebar P is capable of a slight oscillating movement in a verticalposition by means of a spring. I

\Vhen the angle-lever i i is thrown out of normal position by theoperation of the bar P and lever m, the lower arm, t, of the saidangl'e-lever bears against the projection pen the bar I" and holds itdown,.so as to keep the catch, m? clear of the lower end of the lever m.When the angle-lever is tripped by the projection a on the disk h, thearm 1' will be elevated, permitting the lever m to spring under its end,and releasing the pressure upon the plOJGGllOll 2), allowing the bar Pto be elevated,

so that the catch an will engage the lower end.

of the lever m, so that the lever on will be tripped by said catch m atthe next ile'oression of a key-lever. v

The letter G indicates alever, iulcrumed at which is adapted to bethrown into and out position by means of suitable springs.

g, its upper end bearin g against the cam Den the sleeve J To said leveris connected one end of a reciprocating bar, F, to the other end ofwhich is attached thepunch-head A. Said bar and lever are held'in anormal position by means of a spring, k, and are shifted so as tooperate the punch-head by the cams L, when a key is depressed and thesleeve J is rotated by the revolving shaft I.

The letter E represents the key-levers, which are fulcrumed at e andextend forward to the front of the-apparatus, terminatmgin a series ofkeys, E. Said levers are held in anormal The letter 0 represents a.series of end on a rod, 0, the opposite ends being fitted into a slidingrack-bar, .D. The said supplementary levers are arranged directly overthe key-levers E.

To the rear ends of the key-levers are secured transverse pieces f,which serve to raise the supplemen tany levers or bars 0 upon thedepression. of the keys.

These pieces f are locatedsuccessively nearer the ends of therespectivelevers as they recede from the fulcrums of the punch-selectingbars, as shown 8o supplemen tary levers or bars havn'ig bearings at onein Fig. 1 of the drawings, in order to elevate the said punch-selectingbars the same distance-at the depression of each key, asmore fullyhereinafter specified.

The letter B indicates the punch-selecting bars, which extendtransversely over the ends of thesupplementary levers or bars 0, and arepivoted at one end, as indicated at b. The opposite ends o'fisaid leversor bars are shaped to correspond with the punches, so that when they areelevated and brought opposite the ends of the said punches they willactuate them in proper. order to make the necessary perforations in theslip of paper. The lower edges of these punch-selecting bars are notchedor recessed, as indicated in Fig.5, in such relation to the keys andsupplementary bars that when a punch-selecting bar is not required toactuate the proper punch in the formation of a perforation thesupplemental lever or bar will be thrown into the notch or recess as itis raised, leaving such punch-selecting bar in a nornialpositionandelevating. theother punch-selecting bars to operate in conjunction withthe punches to form the perforations for producing the'requiredcharacter.

The. selection of the punch-selecting bars or levers, l1owever, furtherdepends upon the position .given' to the supplemental levers, as

ceases 2 Stand which is located transversely under the key-levers Thedepression of certain keys, serves to oscillate said frame, giving areciprocatin g movement in a backward direc 'tion to the arm as, whichcarries the ,pawl I into, the next tooth of'the ratchet-wheel W.

Upon relieving the key of the pressure and releasing it the frame isreturned to its normal position by the spring S,.thus throwing the armand pawl in to their normal positions and moving the cam-wheel forwardto the extent of one tooth.

The cam-wheel W is prevented from moving backward by the pawl P actingin and upon the ratchet-wheel W.

The reciprocating rack-bar D carries a pin, to, which is operated bymeans of the cams on the cam-wheel W and the spring 20 to ,move saidraelebar back and forth at each depression of the keys and shift thesupplemental bars to the right or lefta given distance, and change thepositions of the respective supplementary bars or levers (J, in order toalternate the punch-selecting bars or levers, said supplementary levers,when in position to the right, serving to elevate one series ofpunch-selecting levers, and when in position to the left to releasethefirst-mentioned bars and elevate others to act in conjunction with thepunches.

As it is essential for the system herein mentioned that the compouentperforations forming the integral perforation representing thecharacter shall alternate, it becomesnecessary that the polarityinterchange shall be effected when the integral perforations consist ofan uneven number of component parts. If the integral perforation for acharacter, as is shown at S, Fig. 9, consists of an even number, then nochange occurs for the next letter. If, however, the perforations areunequal, as at I I, Fig. 9, then achange must occnrfor the next letter,the change being made only when an uneven mnnber of, punches are used,and this occurs only on certain characters, as is well known, in whichthe key-levers of such characters rest on the frame It, so that thedepression of the key will swing the frame and actuate the devices, asaforesaid.

The key-levers of such letters that require only an uneven numberofpunches to make the character are provided with a recess, as shown at10, Fi g. 3, that will permitsuch levers, when depressed, to pass overthe frame R.

A represents a punch-head, carrier, or support for the punches a. Saidpunch-head is supported in position opposite the punch-selecting bars inany suitable manner, and is so arranged that a reciprocating movementmay be given to said punclnhead by the rod F, attachedto the upright armG, which is pivoted at y, and'has a roller, g, secured to it. Saidroller giiiipinges or rests upon the cam L, and is held firmly thereonby the spring k, as before mentioned. As the cam L is revolved a forwardmotion is given to the punch-head A by the action of the lever G and rodF, the

spring 7.- scrving to return the punclnhead to its normal positionimmediately after the point of the cam farthest from its axis has passedthe roller g.

In lieu of the spring I. for returning the punch-head to place, a secondcam or eccentric maybe used, thereby giving a positive and easyto-andfro motion of the punch-head by the same power and with the leastshock to the parts, and with but little noise.

Attached to the punch head or carrier is a metal bar, Z, which passesacross and between the punches 0. 1, lit-ting into the recesses in thesame, the bar Z serving to keep the punches (to clear of the bars 15when at rest. Attached to the frame or support I) is a bar, y, similarto the bar Z, which serves to draw the punches from the die 11' as thepunch-carrier returns to place.

By the use of the pieces 1/ and Z springs that are objectionable forreturning the punches are dispensed with and a positive and reliablemovement obtained.

While we have shown but six punc1i'es three in each row-it is wellunderstood that form the perforated characters.

The letter Y indicates a series of auxiliary bars, pivoted at b to thesupport, and parallel with the punch-selecting bars 13. The saidauxiliary bars are provided with shoulders r near their forward ends,which are formed at varying distances from said ends, for the purpose ofregulating the movement of lever V. The arm V is secured by a shoulderedscrew to a support, T, and the arm tis pivoted to a support, t andcarries a pawl, P', which engages and operates a ratchet-wheel, W seasmany maybe used as may be required to cured to a drum, S, journaled on asupport, d. 4

The said arm V is connected to an arm, 2, by means of a link, V, so thatthe two will move together. The arm V is also seemed to arod, U, whichis connected to an oscillating lever, u, fulcrumed at c The arm itcarries a fric-. tion-roller, a, which bears against the cam M onthesleeve J. As the said cam M is rotated the rod U is drawn back fromthe punches by a spring it until caught by one of the bars Y, whichserves as a stop to limit the movement of the arm V and control thedistance of its oscillation, and regulate the feed of the paper tocorrespond to the length of the perforations for each particularcharacter, the said rod being driven forward by the cam M after beingarrested by the bars Y, giving a partial rotation to the drum S by theaction of the pawl P in connection with theratchetwheel W'. A roller, 8,is arranged to bear against the fillet of paper and press it against theperiphery of the drum S, so as to draw it through the die ateachmovement of said drum and present a fresh portion of the paper tothe punches, the movement of the paper, as before stated, depending uponthe movement of the arm \r,

which is regulated by the spacing-bars, whichare elevated one at a time,the particular spacing-bar elevated depending upon the length of theintegral perforations to produce a given character.

In the several diagrams-indicating the perfo-' rated strip, the letter aindicates the.component parts of the integral perforations representingthe characters, which alternate, as

clearly shown in Fig. 6, from one line to the the component parts oftheintegral perfora tidns require to be reversed, as indicated by. theintegral perforations representing the let ter S,'l3ig. 6, in order thatthe perforations may alternate properly.

In operation the action as follows Motion being imparted to the mainshaft I by any suitable power, upon depression ofa key-lever bearing onthe frames Q R the same are depressed, and the following movements takeplace: The frame Q, upon being depressed, carries forward the c'onnecting-rod r which oscillates the bell-crank lever q, giving a backwardmotion to the catch on of rod P, which trips the oscillating stopanchorm, which permits the hell-crank lever t t" to be thrown into positionshown in Fig.

-4. The arm 23, disengaging from the clutch-h and resting upon thestop-pin p serves as a lock to the stopanchor m, while the point i restsupon the surface of the flange H of the sleeve L. As the arm I isdisengaged from the clutch h the clutch is thrown down upon andintotheratchetwheel jby the spring I, and revolves therewith onecomplete revolution at each depression of a key, and is thrown :out ordisengaged therefrom by the cam n in its revolution coming against thearm tand throwing the arm trip 'into the path of the clutch It, where itis held by the stopanchor m, being thrown by the spring 8'" against thepinp" and underthe arm '5, so that i acts as a stop to the clutch h.Simultaneously with the depression of the frame Q the frame It isdepressed, moving the rod 1' attached thereto and the arm X forward, and

consequently the pawl 12, which is made totake another tooth in theratchet-wheel W, the wheels W and W being held in place by the stop-pawlp Simultaneously therewith the leverE of the key, depressedat the pointf, raises one of the supplementary bars'G, which in turn raises one ormore of thepnnchselectin g bars 13 and one ofthe ieed-regulatiug bars Y.It will be perceived, then, thatthe depression of the frames Q R, theaction of the devices r q I p, M 'i i h and devices r o 2 and theraising of the bars Q B Y all occur in the same instant or period oftime.

of the apparatus is" Immediately upon the clutch taking into therevolving ratchet or spur wheel j the said clutch and the camson thesleeve J become a part of the shaft I, and revolve therewith, and thefollowing movement-s take place: The cam L acts upon the roller 9 on;the lever G, moving, by means of the connecting-rod. F, thepunch-carrier forward and the punches up to and against thepunch-selecting baRS that have been raised, thereby driving the punchesinto the die at and perforating the paper, the-spring is serving tothrow thep'un'clr carrier back to place immediately as that part of the.cam farthest from the axis has passed in its revolution the rollerg'.Simultaneously with the movement of the cam L the cam M changes itsposition and permits the spring u to contract and move the rod to 'andthe arm Vback from the paper until. the arm V is stopped by theraised-paper feed-spacing bar Y. The cam L and cam M are so arranged inrelation to each other that immediately after the cam L has carried thepunch-head forward and perforated the paper, and permitted-the return orpartial return. of the punch-carrier and the withdrawal of the punchesfrom the paper, the cam M, in its revolution, drives the rod-U, arm Vand t.forw ard, partiallyrevolvin g the roller S by the action of thepawl p on the ratchet-wheel W", the movement of the paper dependingupon? the backward movement ofthear-m V, which is regulated by the barsY, as hereiubefore explained. p a

it will be observed-that the above-described operations take place uponthe depression of the key.

The operations and movements that occur when the key is released are asfollows: The frame (,3 is returned to place by the spring 3, therebycarrying the catch on by a forward lateral motion into normal position,as shown 'in Fig, 2. Simul-taneouslytherewith the frame it is returnedto place by the spring 8 Fig.3, which carries forward the rod 1', arm X,and

pawl 12", Fig. 5, driving the compound camwheel by means of theratchet-wheel W, the wheel W, in turn, in its movement acti n g on thepin w in the rack-bar D, and held against W by the spring a, carriestherack-bar D and supplementary bars 0 to the right or left, therebychanging the position of the bars 0 in relation to the levers E and barsB. Shouldnow the same key be again depressed thesame movements wouldoccurand the same results be obtained, excepting only that, the positionof the bars 0 having been changed in relation to the bars B and leversE, different punch-selecting bars B would be raised and difierentpunches used; and if, for instance, the character punched had been asshown in Fig. 10, upon repeating of the same they would appear asshown'in Figtll, the first component part of the integral perforationrepresenting the character being in one case in the top line of rowperforations, and in the other case inseries of punch-selecting thebottom row, the same being caused by using the first top punch first inone case and the first bottom punch first in the other case.

It will be observed that the above explanation is only in reference tosuch keys that bear upon the frame R. It applies, however, to all thekeys, with this exception, that such keys that are provided pass overthe frame B, when they are dcpressed and donot operate the same, so thatthe mechanism connected with R is not operated, and the position of thebars 0 remain unchanged unless a hey is depressed that bears on theframe R.

We do not limit ourselves to the method shown of changing the positionof the bars 0, as there are many other methods ofefl'ecting the same.Neither do we confine ourselves to the precise method of controlling theclutch It, as various other devices may be used without; departing fromthe general principle.
